Die Protonierung eines Mesitylenrings durch das stark saure Areniumcarboran [CH 3 C 6 H 6 ][CHB 11 Me 5 Br 6 ] löst eine Reaktionskaskade aus, die zu einem stabilen β‐Silylallylkation führt (siehe Bild, H gelb, C blau, Silylallylgruppe rot). Dass die Triebkraft der Reaktion ausreicht, um einen stabilen aromatischen Ring zugunsten einer kationischen reaktiven Zwischenstufe zu zerstören, ist bemerkenswert.
